The receipt or receipts of the Secured Party for such funds so paid to it by the Commodity Intermediary shall, as to the Commodity Intermediary, operate as the receipt by the Debtor as fully and as completely as if funds had been paid to the Debtor in person and receipted for by the Debtor. Entitlement Orders.

Nothing herein contained shall be construed so as to prevent the Debtor from remaining the owner, subject to the interest for the Secured Party as it may appear, of the Trading Account. Until the Secured Party elects to the contrary and delivers notice of such election in writing to the Commodity Intermediary, the Debtor may make such additional transactions in the Trading Account as the Commodity Intermediary shall be willing to accept for execution and/or clearance. In the event the Secured Party does make such election and delivers such notice in writing to the Commodity Intermediary, the Debtor shall not thereafter execute any transactions in the Trading Account, and the Commodity Intermediary shall cease complying with orders or other directions concerning the Trading Account originated by the Debtor.

Commodity Intermediary of notice of such election and if directed by the Secured Party, the Commodity Intermediary will use commercially reasonable efforts to cancel open orders that have been entered by the Debtor through the Commodity Intermediary which have not yet been executed. If the Commodity Intermediary is unable to cancel such orders before they are executed, the transactions will be considered valid and binding on the Debtor and the Secured Party and the Debtor and the Secured Party shall have no claim against the Commodity Intermediary in connection with such transactions. In the event that orders are executed for the Debtor s Trading Account by a third party pursuant to the terms of a give-up or similar agreement among the Debtor, the Commodity Intermediary and such third party, the Commodity Intermediary will use commercially reasonable efforts, subject to the terms of such agreement, to notify such third party that the Commodity Intermediary will not thereafter accept trades executed by such third party for clearance into the Debtor s Trading Account. (c) (d) (e) (f) (g) SECTION 5. The Commodity Intermediary has not entered into any agreement with the Debtor or any other Person purporting to limit or condition the obligation of the Commodity Intermediary to comply with Entitlement Orders originated by the Secured Party. If at any time the Commodity Intermediary shall receive any Entitlement Order from the Secured Party, the Commodity Intermediary shall comply with such Entitlement Order without further consent by the Debtor or any other Person, notwithstanding that such Entitlement Order may conflict with any instruction or notification by the Debtor or any other Person. The Commodity Intermediary need not investigate whether the Secured Party is entitled under the Secured Party s agreements with the Debtor to give an Entitlement Order or a notice of exclusive control. The Commodity Intermediary may rely on notices and communications it reasonably believes are given by the appropriate party. The Commodity Intermediary will not be liable to the Secured Party for complying with orders or other instructions from the Debtor that are received by the Commodity Intermediary before the Commodity Intermediary has received and had reasonable opportunity to act on the Secured Party s notice of election of exclusive control. The rights and powers granted to the Secured Party under this Section 4 and the other provisions of this Agreement have been granted in order to perfect the Secured Party s Lien with respect to the Trading Account and the Trading Account Property, are powers coupled with an interest, and will not be affected by the bankruptcy of the Debtor or by the lapse of time. Additional Rights of the Secured Party Whenever the Secured Party deems it necessary for its protection, it shall be entitled, without the consent or concurrence of or prior notice to the Debtor, to direct the Commodity Intermediary to liquidate any of all then outstanding open positions in the Trading Account and to direct the Commodity Intermediary to pay to the Secured Party any credit balance as shall exist in the Trading Account after such liquidation and after the payment to the Commodity Intermediary of all indebtedness of the Debtor to the Commodity Intermediary in connection with transactions in the Debtor s accounts with the Commodity Intermediary. The Debtor shall be liable to the Commodity Intermediary for any debit or deficit that may be created when the Secured Party initiates a liquidation. If the Commodity Intermediary requires additional margin for an open position, the Secured Party shall advance to the Commodity Intermediary on behalf of the Debtor such amounts as may be required by the Commodity Intermediary to margin such position, or shall give the Commodity Intermediary reasonable notice of its intent not to advance such margin as stated below; provided, however, that the Debtor in all respects shall remain liable to the Secured Party for any amount so advanced. The Secured Party shall notify the Commodity Intermediary immediately, and in no event more than one business day after the Commodity Intermediary requests additional margin, if the Secured Party determines not to make any further advance or extension of credit on behalf of the Debtor.

In the event of any assignment by the Secured Party, the Secured Party shall give written notice of such assignment to the Debtor and the Commodity Intermediary and the assignee will thereupon be the Secured Party hereunder, with all the same rights, duties and privileges as though originally named as the Secured Party hereunder. SECTION 12. No Adverse Claims. Except for the claims and interest of the parties hereto in the Trading Account and the Trading Account Property, the Commodity Intermediary does not know of any claim to, or interest in, the Trading Account or the Trading Account Property. If any Person notifies the Commodity Intermediary that it is asserting any Lien or adverse claim (including, but not limited to, any writ, garnishment, judgment, warrant of attachment, execution or similar process) against the Trading Account or the Trading Account Property, the Commodity Intermediary will promptly notify the Secured Party and the Debtor thereof.
